Hi, I’m coding and I’m getting this error:
**Assets/Standard Assets/CrossPlatformInput/Scripts/AxisTouchButton.cs(22,56): error CS0117: `UnitySampleAssets.CrossPlatformInput.CrossPlatformInputManager' does not contain a definition for `AxisExists’**
This is my code:
using System;
using UnityEngine;
using UnityEngine.EventSystems;
using UnitySampleAssets.CrossPlatformInput;
namespace UnityStandardAssets.CrossPlatformInput
{
public class AxisTouchButton : MonoBehaviour, IPointerDownHandler, IPointerUpHandler
{
// designed to work in a pair with another axis touch button
// (typically with one having -1 and one having 1 axisValues)
public string axisName = “Horizontal”; // The name of the axis
public float axisValue = 1; // The axis that the value has
public float responseSpeed = 3; // The speed at which the axis touch button responds
public float returnToCentreSpeed = 3; // The speed at which the button will return to its centre
AxisTouchButton m\_PairedWith; // Which button this one is paired with
CrossPlatformInputManager.VirtualAxis m\_Axis; // A reference to the virtual axis as it is in the cross platform input
void OnEnable()
{
if (!CrossPlatformInputManager.AxisExists(axisName))
{
// if the axis doesnt exist create a new one in cross platform input
m\_Axis = new CrossPlatformInputManager.VirtualAxis(axisName);
CrossPlatformInputManager.RegisterVirtualAxis(m\_Axis);
}
else
{
m\_Axis = CrossPlatformInputManager.VirtualAxisReference(axisName);
}
FindPairedButton();
}
void FindPairedButton()
{
// find the other button witch which this button should be paired
// (it should have the same axisName)
var otherAxisButtons = FindObjectsOfType(typeof(AxisTouchButton)) as AxisTouchButton[ ];
if (otherAxisButtons != null)
{
for (int i = 0; i \< otherAxisButtons.Length; i++)
{
if (otherAxisButtons\_.axisName == axisName && otherAxisButtons _!= this)_\_
_\* {\*_
_m\_PairedWith = otherAxisButtons\*;
\_ }
}
}
}
void OnDisable()
{
// The object is disabled so remove it from the cross platform input system\*
\* m\_Axis.Remove();\*
\* }
public void OnPointerDown(PointerEventData data)
{\_
if (m\_PairedWith == null)
\_ {
FindPairedButton();
}
// update the axis and record that the button has been pressed this frame\*
m\_Axis.Update(Mathf.MoveTowards(m\_Axis.GetValue, axisValue, responseSpeed \* Time.deltaTime));
\* }
public void OnPointerUp(PointerEventData data)
{
m\_Axis.Update(Mathf.MoveTowards(m\_Axis.GetValue, 0, responseSpeed \* Time.deltaTime));
}
}
}\*
Note: It’s from the asset store\__

lets start with [Using code tags properly - Unity Engine - Unity Discussions](http://forum.unity3d.com/threads/using-code-tags-properly.143875/)
as the error says, “AxisExists” doesn’t exist… so you’re likely missing a file somewhere, or the function has been misspelt?
